Lost Dog: Looks Like Shepherd Mix - Help!

Our dog Harley got out friday 4/5 and we’ve been looking everywhere and haven’t been able to find her. She’s a medium size about 40-50lbs, black and brown markings, female. She’s a mutt so I can’t tell you the breed but everyone mistakes her for a German shepherd, min pin or Rottweiler mix because of her coloring. She’s wearing a light color collar with flowers on it, not a pattern but actually on the collar. If anyone sees or found a dog that is close or matches this description please let me know. My phone number is (805) 744-9173. I’ve attached photos for reference as well.
